ANTISEPTIC ATTACHME NT FOR TELEPHONE-MOUTHPIECES.

SPECIFICATION forming-part of Letters Patent No. 754,057, dated March 8,1904.

' Application filed April 2' 7, 1903. Serial No. 154,427. (No model.)

To all whom it may concern.-

Be it known that we, WILLIAM M. ENGLISH and ARTHUR H. TEN BROECK,citizens of the United States, residing at San Francisco, in the countyof San Francisco and State of California, have invented certain new anduseful Improvements in Antiseptic Attachments for Telephone-Mouthpieces,of which the following is a specification.

Our invention relates to improvements in antiseptic attachments fortelephone-mouthpieces, the object of our invention being to provide adevice of this character which can be cheaply constructed and readilyattached to any size of mouthpiece and which will effectively destroybacteria and noxious germs in the mouthpiece.

Our invention therefore resides in the novel construction, combination,and arrangement of parts for the above ends hereinafter fully specified,and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of themouthpiece with the attachment'secured thereto. Fig. 2 is a longitudinalsection thereof. Fig.3 is a perspective view of the shell detached. Fig.4 is a perspective view of the ring detached.

Referring to the drawings, 1 represents the mouthpiece proper, which isof the ordinary bell-shaped form. Within said mouthpiece is placed aconoidal or bell-shaped shell 2, of metal or other inflexible material,the rim of the outer or larger end of'said shell being curled outwardand backward through substantially half a revolution, as shown at 3, to

form an annular external trough at said outer end. In this trough isplaced a ring 4:, of absorbent material, which is saturated with anantiseptic. The shell is then placed within the mouthpiece, so that thecurled edge of the rim abuts against its outer end. It is securedthereto in any desired manner, the means for securing the same not beingan essential feature of our invention. In the present instance we haveshown tongues 5 secured upon the rim and extending inward, said tonguesbeing bent over a ring 6, which is passed around the mouthpiece, therebyfirmly clamping the shell in position.

The shell is perforated, as shown at 7 and the vapors of thedisinfectant escape through said perforations into the interior of theshell, thus thoroughly disinfecting the mouthpiece. At the upper portionof the curled rim is provided an aperture 8, which can be used for thepurpose of dropping the liquid antiseptic upon the absorbent material inthe trough. At the bottom of said curled rim are provided a number ofsmall apertures 9, which serve as drain holes to drain excess ofmoisture which may be caused by condensation of the breath. Theseapertures 8 9 also serve the additional purpose of admitting air to passthrough the absorbent material, thereby assisting in the volatilizationof the antiseptic liquid. At the inner end of said shell is secured ascreen 10, which excludes moisture from the diaphragm of the telephone.

The above attachment being of metal can be made at a very small cost andcan be attached to any of the ordinary forms of mouthpieces.

We claim 1. In combination with a bell-shaped telephone-mouthpiece, aninner bell-shaped shell of ihflexible material within the mouthpiece,having its outer or larger rim curled outward and back throughsubstantially half a revolution to form an annular external-trough, therear edge of the trough resting against the front of the mouthpiece anda ring of absorbent material saturated with an antiseptic in saidtrough, said shell being perforated Within the mouthpiece, substantiallyas described.

- 2. In combination with a bell-shaped telephone-mouthpiece, an innerbell-shaped shell of inflexible material-within the mouthpiece, havingits outer or larger rim curled outward and back through substantiallyhalf a revolution to form an annular external trough, the rear edge ofthe trough resting against the front of the mouthpiece, and a ring ofabsorbent material saturated with an antiseptic in said trough, saidshell being perforated within the mouthpiece, the upper portion of said10 ring around the mouthpiece and the tongues secured to the shell andbent around said ring, substantially as described.

In Witness whereof We have hereunto set our hands in the presence of tWosubscribing Witnesses.
